tles, jars or the like and has for its'object to provide a simple andeffective closure which can be easily and quickly applied to a bottle,jar or the like and which will absolutely seal the same and which can bereadily removed without injury to.the clo- FWith this object in view theinvention consists in the novel construction of the closure and in thenovel construction of the bottleneck or mouth to receive the same.

The invention also consists in certaincombinations of parts, all ofwhich will be first fully described and afterward specifically pointedout in the appended claims:

Referring to the accompanying drawing: Figure 1 is a vertical sectionalview taken through a bottle n'eclc illustrating the closure in operativeposition. Fig. 2 is an'elevation of the same. Fig. 3 is a top plan viewof ,the bottle neck. Fig. 4 is an elevation of the bottle neck with thecap or closure removed.

Fig. 5 is a top plan view of the cap or 010- sure, and Fig. 6 is a planview of the sealing disk. Like numerals of reference indicate the sameparts throughout the several figures in which;

1 indicates the neck of a bottle, jar or the like, and 2 indicates a capor closure. The neck 1 of the bottle, jar or the like is provided atitsmouth with an interior annular shoulder 8, said annular shoulder 3 beingformed on an angle as shown in Fig. 1 inorder to present a sharp edge 4for engagement with the sealing disk 5, said sealing disk 5 being of anysuitable material but preferably of a wood pulp board 6 having a layerofwaterproof paper 7 under the same in the manner as shown in Fig. 1.

Longitudinally of the bottle neck and exand the annular shoulder 3 are alurality of grooves 8 as shown in Fig. 3, said grooves 8 terminating atthe annular shoulder 3 in the manner as illustrated in Figs. 1 and 3.Exteriorly of the bottle neck I provide a plurality of vertical grooves9 which extend to a point below the said annular shoulder 3, the saidbottle neck at the mouth thereof being slightly enlarged at 10 in theing, the bottom portions of the said enlargement bein inclined at 11 to,form'inclined planes in t e manner as shown in Fig. 4.

Referring now to the cap or closure it will be seen that the same isprovided with a relatively dee central depression 12, the wall 13 ofwhich is annular and snugly fits the internal surface of the bottle neckin the manner as shown-in Fig. 1, while the exterior portion of the capor closure 2 is pro.- vided with aplurality of corrugations 14 so as tobetter enable manipulation of the cap, while a plurality of lockingelements 15 are provided at theextreme bottom edge 1 and 2. 1

Aswill appear from Fig. 6 the sealing disk 5 is provided at itsperipherywith a [plurality of extensions 16, which extensions enter thevertical grooves 8 in the bottle neck in order-to hold the said disk 5against r0- tation while applying or removing the cap or "closure. 1 4Having thus fully described the several parts oft-his invention itsoperation is as follows: The bottle neck being constructed in the manneras shown'and described the cap or closure is applied by depressing thesame so thatthe locking elements 15- pass downwardly through theexterior vertical the inclined bottom surfaces or. edges 9f the sealingdisk 5 being in proper position. and

3 within the bottle neck the cap or closure is given a turn which causesthe locking elements 15 to engage the inclined surfaces 11 on the bottomof the enlargement 10 which causes the depressed central portion of thecap or closure to engage and force the sealing disk into intimateengagement with the annular shoulder 3..within the bottle neck, thesharp edge of said annular shoulder on:

manner as shown in the accompanying drawexternal enlargement of thebottle-neck. Thein engagement with the annular shoulder tending betweenthe end of the bottle neck of the cap in the manner as shown-in Figs.--

grooves 9 in the bottle neck and take under tering the sealing disk inthe manner as shown in Fig. 1. When the cap is applied the extensions 16on the sealing disk 5 enter the internal vertical grooves 8 in thebottle neck and as the cap or closure is turned to lock the cap orclosure the sealing disk 5 is held stationary relative to the annularshoulder 3 so that the same is not mutilated.

By means of this construction the cap or closure can be applied andremoved an indefinite number of times without injuring the sealing diskand without effecting the sealing qualities of the same.

Having thus fully described the invention What I claim as new and desireto secure by Letters Patent of the United States is 1. A bottle and capcomprising a bottle neck having an enlarged portion at the mouththereof, a plurality of vertical grooves in said enlarged portion, thebottom surface of said enlarged surface being inclined, the interior ofsaid neck being pro- Vided With an annular shoulder, said annularshoulder being inclined to present a sharp edge, the said bottle neckbeing also provided on its interior With a plurality of vertical groovesarranged 1 between the mouth of the bottle and the said annularshoulder, a cap having a central depression to fit the interior of thebottle neck, a sealing disk arranged between said central depression inthe cap and the annular shoulder in thebottle, the said cap being alsoprovided with a plurality of locking elements adapted to enter the saidexternal grooves in the said enlarged portion of the bottle neckand toengage the inclined surface of the said enlarged portion to lock the capin position and to force the said sealing disk into intimate engagementwith the said annular shoulder within the bottle neck, the said sealingdisk being provided with a plurality of extensions on its periphery toenter the said vertical grooves on the interior of the bottle neck tohold the said disk against rotation Within the bottle neck when the saidcap is rotated on the bottle neck, substantially as described.

2. A bottle and closure therefor, the neck of said bottle having anexternal enlargement thereon, the bottom surface of said enlargementbeing inclined, the interior of said bottleneck having an annularshoulder therein provided with a sharp edge, said bottle-neck interiorhaving a plurality of vertical grooves therein extending from the mouthof the bottle to said shoulder, a sealing disk adapted to fit within thebottleneck and having perimetric extensions thereon received by saidvertical grooves, said sealing disk resting upon said annular shoulder,said closure having a centrally (lepressed portion entering thebottle-neck and engaging said sealing disk, said closure also having atits bottom-edge locking elements adapted by turning said closure to takeunder and engage the inclined surfaces of said external neck-enlargementto cause said centrally depressed portion of the closure to engage andforce said sealing disk upon the sharp edge of said annular shoulder.

In testimony whereof, I aflix my signature, in presence of twowitnesses.

I JOHN S. ALSTON.
